Abstract

PROBLEM TO BE SOLVED: To facilitate formation of heat insulating layers on both faces of a face bar and dispense with a storage place for members in the course of manufacture by disposing a heat insulating part with heat insulating material held from the surface by sheet material, at the rear face of a panel base body formed of the face bar and heat insulating material disposed on the surface of the face bar, to form a heat insulating panel. SOLUTION: A heat insulating panel A is composed of a panel base body B and a heat insulating member C. The panel base body B is composed of a face bar 1, a heat insulating layer 2 disposed on the surface of the face bar 1, and a covering member 3 disposed on the surface of the heat insulating layer 2. The heat insulating member C is formed by holding heat insulating material 11 from the front and rear faces by first sheet material 12 and second sheet material 14. In a process of forming the heat insulating panel A, end pieces 13, 15 are first bent, and the end part of the heat insulating material 11 is cut off if necessary to adjust dimensions. The heat insulating member C is then fitted to the rear face of the face bar 1 of the panel base body B through the first sheet material 12 to form the heat insulating panel A. Formation of the heat insulating layers 2 on both faces to the face bar 1 is therefore facilitated, and a storage place for members in the course of manufacture can be dispensed with.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel which forms a load-bearing wall while forming a heat insulating layer on a building or a building.

[0002]

2. Description of the Related Art Conventionally, a heat insulation panel for forming a heat-insulating layer on a wall of a building or building while forming a bearing wall and forming a heat-insulating layer on both front and back surfaces of a plate material in summer,
An example of a heat insulating panel configured to prevent the occurrence of dew condensation on the boundary between the heat insulating layer on the front and back surfaces and the plate material throughout the winter season is, for example, Japanese Utility Model Laid-Open No. 5-83113. That is, it is composed of a plate-like member that forms a structural member between pillars, an outer heat insulating material located on the outdoor side of the plate-like member when laid, and an inner heat-insulating layer located on the indoor side of the plate-like member. Was something.

[0003]

The above-mentioned heat-insulating panel is manufactured by foaming a synthetic resin on one side of the plate-like member or by attaching a predetermined heat-insulating material to the heat-insulating panel. After forming the heat insulating layer, the heat insulating layer must be formed on the other surface of the plate-like member by turning it upside down in the same manner. A large space for temporarily storing the plate-shaped member having the heat insulating layer formed on one surface is required. In the process of forming the heat insulating layer on the other surface while forming the heat insulating layer on one surface of the plate-like member,
There is a possibility that the first heat insulating layer may be damaged. Serial production is difficult. And so on.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a heat insulating material is provided on the back surface of a panel base comprising a face material and a heat insulating layer disposed on the surface of the face material. We propose a heat insulation panel with a heat insulation member sandwiched between sheet materials from the back.

[0005]

Since a separately formed heat insulating member is arranged on the back surface of the panel base material provided with a heat insulating layer on the surface in advance, the panel base and the heat insulating member can be manufactured at the same time and attached later. It is possible to easily form a heat insulating layer on both surfaces. Also, since the production of the panel base and the heat insulating member can be performed in parallel, there is no particular need for a place for storing the member being manufactured,
Can be produced continuously. Further, since the heat insulating member is simply attached to the back surface of the panel base material, the heat insulating layer is not damaged.
